That's pretty useless info. How about the model (Dimension, Inspiron, Optiplex, etc) & model number (580, 2400, SX260, etc) of your Dell?
From the Dell website:
"Alert! Previous attempts at booting this system have failed at checkpoint [nnnn ]. For help in resolving this problem, please note this checkpoint and contact Dell Technical Support — The computer failed to complete the boot routine three consecutive times for the same error. Contact Dell and report the checkpoint code (nnnn) to the support technician."
